What is the R Language?
It is an open-source language available for utilization on a variety of operating systems and platforms. It was developed by Ross Ihaka and Robert Gentleman in New Zealand and includes a command-line interface. R language is highly extensible, integrated with FORTRAN, Python, C++, and .NET, and available as free software. It is used for data manipulation, calculation, and visualization purposes. The language provides users with objects, functions, and operators and can handle big data for statistical modeling and data analysis.
It also has wide applicability in clustering, statistical tests, classification, and linear and non-linear modeling. The R language is the implementation of the S programming language. Moreover, currently, it is among the hot trends and, hence, is the most preferred programming language in Data Science.
Features of R Language
Holding wide importance in multiple fields including Data Science, the features of R are worth the discussion. Here are those:
- Comprehensive environment for multiple functions
- Allows distributed computing
- Support towards extensions, complex statistical calculation, and statistical modeling
- Easy to handle and understand
- Runs code in the absence of a compiler
- Coding interface with DBMS
- Contains quality visualizaiton libraries
- Allows advanced data analytics
- Widely used in both industry and academics
- Handles a variety of data
- Utilized for web scraping
- Allows direct operations on vectors, eliminating the requirement of looping
- Easily extracts data from multiple platforms and formats
Role of R Language in Data Science
Now you are well-aware of what is the programming language R and its features. We can head towards its role in Data Science.
- The R language is primarily preferred for its statistical and graphical techniques that allow efficient statistical analysis and aesthetic data visualizaiton.
- It offers compatibility in cleaning, importing, and data analysis.
- It comprises an Integrated Development Environment or IDE that eases the handling of software packages
- RStudio is the IDE for R that offers a syntax highlighting editor useful for code execution.
- It is capable of unstructured data analysis and interfacing with the NoSQL database
- It supports Data Science processes such as data wrangling, web applications, and non-vector based statistical calculations.
- The different packages of R are suited for multiple industries
- It is an advanced language capable of performing complex statistical modeling
- For candidates clear with fundamentals, handling R is comparatively easier

Real-Life Applications of R in Data Science
The technological giants have incorporated R for their Data Science based tasks. Here are a few examples of the same:
IBM: The open computing platform of IBM with the name IBM Watson primarily uses the programming language R. IBM also joined the R consortium group.
Google: Google utilizes R in multiple of its projects. While it is used for economic forecasting and efficiency in advertising, R is also preferred for analytical operations. An example of the latter is the Google Flu Trends project. Moreover, the combination of Google Analytics and R available as the RGoogle Analytics package is suggested for efficient statistical analysis and better data visualizations.
Novartis: The pharmaceutical company uses R for clinical data analysis.
Uber: Uber also uses R for statistical analysis. It uses Shiny, an R package, for charting components.
Facebook: It primarily uses R for social network analytics and behavior analysis for updating status and profile pictures. It figures out the relationship between the users and their behavior.
ANZ: The company utilizes R in the banking sector for analytical solutions such as loan default prediction and credit risk analytics.
T-Mobile: The communication company makes use of R for customer requirement analysis and to provide services accordingly.
BBC: The BBC uses R primarily for all the data visualization related tasks. It even offers training for the employees to leverage the power of R.
